Car Washing Dosing Pumps Without Electric

  Water Powered Automatic Proportional Dosing Pumps    Working principle: The proportional pump takes the flowing pressure water as power, having small water pressure loss, without any other power facilities. It uses water power of the proportional pump as engine which drives the piston and the connecting rod inside the proportional pump, sucks up the liquid additive directly and makes it dissolve in the water flow. This device moves up and down in a cylinder. When pressing out the water, it uniformly sucks the additives loaded at the bottom of the container into the water flow through a tube. Repeat the up-and-down motion until the effect is achieved that the additive is added to the flowing water evenly and constantly.   Specifications: Model: DP2502 Dosage rate: 0.2%-2% Flow rate: 25-2500L/H Working temp: 4-30℃ Water pressure: 0.2-6Pa Coupling: 1" (25mm)   Specifications: Model: DP2504 Dosage rate: 0.4%-4% Flow rate: 25-2500L/H Working temp: 4-30℃ Water pressure: 0.2-6Pa Coupling: 1" (25mm)   Specifications: Model: DPY2502 Dosage rate: 0.2%-2% Flow rate: 25-2500L/H Working temp: 4-30℃ Water pressure: 0.2-6Pa Coupling: 1" (25mm)   Specifications: Model: DPY2501 Dosage rate: 0.2%-1% Flow rate: 25-2500L/H Working temp: 4-30℃ Water pressure: 0.2-6Pa Coupling: 1" (25mm)   Specifications: Model: DPY2505 Dosage rate: 1%-5% Flow rate: 25-2500L/H Working temp: 4-30℃ Water pressure: 0.2-6Pa Coupling: 1" (25mm)   Specifications: Model: DPY2510 Dosage rate: 1%-10% Flow rate: 25-2500L/H Working temp: 4-30℃ Water pressure: 0.2-6Pa Coupling: 1" (25mm)   Specifications: Model: DPY2520 Dosage rate: 2%-10% Flow rate: 25-2500L/H Working temp: 4-30℃ Water pressure: 0.2-6Pa Coupling: 1" (25mm)   Advantages: Works at low flow rate Easy to field maintenance Highly chemical resistant Good blending Highly resistant to UV damage Easy to install No electricity needed Easy to adjust dosing rate Replaceable seals   Application: 1, Horticulture industry: fertilization, storage and pest control for flowers, fruits and vegetables, etc. 2, Animal husbandry: the fixed-ratio health dosing for livestock and poultry, such as chickens, ducks, oxen and pigs. 3,Industrial use: water treatment, chemical engineering, metal processing, and fire control, etc. 4,Constant proportion dilution of special solvents, such as smell removal solvent, cooling solvent and lubricating solvent. 5,Car washing industry, printing industry, hospitals, wine industry and other industries.     Installation and Fixation: 1, Choose the location: the water inlet and water outlet of the dosing pump must match those of the main pipe. 2, Dosing pump must be installed according to the method that the dosing pump is above the fluid intake tube. 3, Fix the dosing pump to a wall or other facilities. 4, Install the water inlet and outlet of the dosing pump according to the direction of water flow, so as to ensure its leakproofness. 5, Install 100-120 mesh screen between the inlets of water valve and dosing pump. 6, When the addition of chemicals is required, close the side branch valves of the proportional pump. The addition of chemicals can be carried out when the valves on both sides of the dosing pump are opened. 7, Click sound will be heard when dosing pump begins to work. At this time, push the air vent valve on the top of the dosing pump and release the valve when small amount of water flows out. In this way, normal operation of doser can be ensured.     Adjust Proportion The dosing pump can adjust the additive proportion in water according to actual situations, so as to achieve the best effect of additive. Specific ways are as follows: 1, Loosen the screw, and take off the U-style adjusting lock from the upper part of the proportional pump. 2, Predetermine the proportion of liquid additive and water according to the proportion of the water scale on the proportional pump. A counterclockwise adjustment is to increase the proportion of liquid additive. A clockwise adjustment is to decrease the proportion of liquid additive. The percentage on the proportional pump is calculated on the basis that the final water yield of the dosing pump is 100. 3, Please turn the regulator until the hole above the U-style adjusting lock is inserted into the notch of the dosing  pump. 4, Press the U-model adjusting lock hard into the upper notch of the dosing pump until each other is locked tightly.     Notice: 1, Make sure that the container holding the liquid additive is not empty during the use of automatic dosing pump 2, Air release valve: It is necessary to press down the air release valve for several seconds to vent the air already  existing inside when initially starting the dosing pump. During this process, there may be a little water flowing out.  Close the valve quickly, after the air is expelled from it. 3,  Make sure the filter plant is installed at the inlet of the dosing pump while installing and using. 4, If the working resistance grows bigger while using, then lubricating oil should be added at the piston to increase the service life. 5, The dosing pump should be washed with clean water after using to reduce corrosion and extend the service life of the dosing pump.
